/*****************************************************************
 *
 * $Log: StVpdCalibMaker.h,v $
 * Revision 1.6  2011/02/23 20:00:52  geurts
 * Change MaxBin for ToT arrays from 60 to 128 (in agreement with the IDL definition of vpdTotCorr)
 * Move the log message that informs the user about the start-timing mode outside the tube loop ... no need to see the same message 38 times.
 *
 * Revision 1.5  2011/01/07 21:28:51  geurts
 * Allow user to "force" VPD-start or startless mode, regardless of dbase setting
 *
 * Revision 1.4  2010/05/12 22:46:51  geurts
 * Startless BTOF self-calibration method (Xin)
 *
 * Revision 1.3  2010/05/06 22:37:41  geurts
 * Remove slower hits (outliers) in VPD timing calculations (Xin Dong)
 *
 * Revision 1.2  2009/11/09 21:26:02  geurts
 * basic doxygen added
 *
 * Revision 1.1  2009/11/09 20:55:54  geurts
 * first release
